Kev ntsuam xyuas qhov kev ua tau zoo ntawm cov khoom noj khoom haus ib puag ncig yuav tsum muaj cov qauv kev sim simulating ib puag ncig ntuj. Lub hom phiaj yog txhawm rau kuaj nws tus nqi biodegradation, qib mineralization, thiab kev nyab xeeb ntawm cov khoom degradation. Cov txheej txheem thoob ntiaj teb xws li ISO thiab ASTM feem ntau siv rau kev soj ntsuam kev tshawb fawb.
Qhov Ntsuas Kev Ntsuas Cov Ntsiab Lus: Txiav txim siab "Kev Txom Nyem Tseeb" los ntawm "Pseudo-Kev Tiv Thaiv Ib puag ncig"
Biodegradation tus nqi
Qhov no yog hais txog kev faib ua feem ntawm cov khoom hloov mus rau carbon dioxide, dej, thiab biomass los ntawm cov kab mob.
Tus Qauv rau Kev Ua Raws Cai: Raws li cov txheej txheem kev tsim khoom (60℃± 2 degree), tus nqi degradation yuav tsum siab dua lossis sib npaug li 90% hauv 180 hnub (raws li ISO 14855-1).
Thaum kawg Mineralization
Qhov no ntsuas qhov℃uas cov organic carbon yog kiag li oxidized rau CO₂, xav txog qhov meej ntawm degradation.
Muab xam los ntawm kev ntsuas tus nqi ntawm CO₂ tso tawm, cov mineralization℃yuav tsum ncav cuag ntau tshaj 90% ntawm cov ntaub ntawv siv.
Disintegration Degree
Qhov no yog hais txog cov khoom muaj peev xwm ua rau lub cev tawg mus rau hauv cov khoom me me thaum lub sij hawm composting.
Cov txheej txheem yuav tsum tau ua: Tom qab 90 hnub, qhov hnyav ntawm qhov seem dhau los ntawm 2 hli sieve yuav tsum tsawg dua lossis sib npaug li 10% (EN 13432).
Kev ntsuam xyuas ecotoxicity
Cov degraded residue yuav tsum tsis txhob cuam tshuam cov nroj tsuag kev loj hlob los yog cuam tshuam cov av microbial tshuav.
Qhov no feem ntau txheeb xyuas siv cov noob germination npaum li cas (piv txwv li, rau cov zaub qhwv, radish) thiab kev ntsuas kev ua pa hauv av.
